An impulse radio transceiver for full duplex ultrawide-band communications. The transceiver comprises an impulse radio transmitter to transmit impulse radio signal pulses, an impulse radio receiver to receive impulse radio signal pulses. Either or both of the impulse radio transmitter and the impulse radio receiver, synchronizes the transmission and the reception of the impulse radio signal pulses for pulse interleaved communications. Pulse interleaving avoids self-interference between the transmitted impulse radio signal pulses and the received impulse radio signal pulses. In addition to pulse interleaved communications, bursts of pulses can be transmitted between two transceivers in an interleaved fashion. Alternatively, two different pulse repetition rates are be used to transmit and receive impulse radio signal pulses simultaneously. Still further, selected pulses of the received or transmitted impulse radio signal pulses are blanked to avoid interference.

A method for full duplex transmission between at least two impulse radio transceivers, comprising the steps of: a. providing a periodic timing signal at a first of the at least two impulse radio transceivers; b. modulating said periodic timing signal using an information signal to output a coded timing signal; c. time delay modulating said coded timing signal to output a modulated, coded timing signal; d. generating an impulse radio signal using said modulated, coded timing signal; e. transmitting said impulse radio signal to the other of the at least two impulse radio transceivers; f. receiving said transmitted impulse radio signal at the other of the at least two impulse radio transceivers; g. generating and transmitting, at the other of the at least two impulse radio transceivers, a further impulse radio signal in response to step f; and h. repeating steps a-g in a synchronous manner for pulse interleaved communications between the at two impulse radio transceivers to avoid self-interference at each of the at least two impulse radio transceivers.
